Discovered a Potentially Habitable 'Sister Solar System'

NASA just announced that they have discovered seven Earth-Sized planets orbiting around the  habitable or 'temperate zone' of a star just 39 light-years away. This is one of the most significant exoplanet discoveries to date. The announcement was made in a live press conference.

NASA is calling the system of planets `sister-solar system` to our own. According to NASA six of the seven discovered planets have masses near to that of Earth and are made of rock and the surface temperature of these discovered planets ranges 0 to 100°C (32 to 212°F). Also, NASA is claiming that some of the planets in the system could be holding liquid water and may be even there is a possibility of Extraterrestrial life.

It is for the first time so many terrestrial planets are seen orbiting around a single star.

This discovery brings hopes that finding a second Earth  is also a possibility. The new exoplanets have been detected orbiting an ultracool dwarf star called TRAPPIST-1, which is located about 39 light-years away from our Sun in the Aquarius constellation.

Astronomers led by Michaël Gillon from the University of Liège in Belgium first detected three exoplanets around the star back in May 2016, using Earth-based telescopes.

But it wasn't until the team studied it more closely using NASA's Spitzer space telescope that they discovered an additional four planets in the system.

Three of the planets lie in the star’s habitable zone. If you aren’t familiar with the term, the habitable zone (also known as the “goldilocks zone”) is the region surrounding a star in which liquid water could theoretically exist. This means that all three of these alien worlds may have entire oceans of water, dramatically increasing the possibility of life.
